CRC
CRC errors indicate that the receiver is unable to synchronize to the CRC-4 frame pattern of the received
E1 signal.
Recommended Actions:
1. Verify the TRACER 64x0 unit and the attached equipment are configured for the same signaling
(M
ULTIFRAMED, UNFRAMED, or FRAMED).
2. Verify the cable connections for the E1 interface are solid.
System Alarms
All active system alarms are displayed on the SYSTEM ALARMS menu page. To identify the current system
alarm present, display the
SYSTEM ALARMS screen and check the alarms fields (FAN SPEED and
TEMPERATURE).
Recommended Actions:
1. Display the SYSTEM ALARMS screen and check the alarms fields (FAN SPEED and TEMPERATURE) to
identify the active alarm.
2. Follow the steps below for the appropriate alarm.
Fan Speed Alarm
Fan speed alarms indicate a physical problem currently occurring with the indicated fan such that the fan
RPM is below the safe operational threshold.
Recommended Actions:
1. Verify the TRACER 64x0 fans are not physically blocked.
Temperature Alarm
Temperature alarms indicate that the internal temperature has risen above the safety threshold.
Recommended Actions:
1. Verify the TRACER 64x0 fans are not physically blocked and are working properly.
2. Verify that the ambient temperature at the physical location does not exceed the recommended
operating temperature (65°C).
LAN LEDs
If the LAN LED is OFF, the TRACER 64x0 is not able to detect an active Ethernet link on the particular
10/100BaseT/TX interface.
Recommended Actions:
1. Check all Ethernet cable connections to verify they are properly plugged in (making sure the tab on the
connector snaps into place).
2. Connect the 10/100BaseT/TX interface to a “known good” Ethernet port to verify the TRACER port is
functioning properly.
3. Try another Ethernet cable.
3. RF ERRORS
RF errors can range from a nonviable microwave path to loose RF connectors.
